Marxism-Leninism

Marxism-Leninism is a communist political philosophy that developed following the Russian Revolution in the 1920s. The philosophy incorporated the beliefs of both Karl Marx and Vladimir Lenin, and it stated that a global revolution was not needed to establish socialism; the concept of "Socialism in One Country" was supported. Marxism-Leninism instead advocated supporting revolutionary groups across the world, overseeing a slow transition from capitalism to socialism, and establishing democratic centralism ("diversity in discussion, unity in action"). The theory was the official ideology of the Communist Party of the Soviet Union during its existence, as well as the countries of China, Cuba, Vietnam, and Laos during the 21st century.
